A RegEx, or Regular Expression, is a sequence of characters that forms a search pattern. RegEx can be used to check if a string contains the specified search pattern. RegEx Module Python has a built-in package calledre, which can be used to work with Regular Expressions. ...
In a usual python string, the backslash is used to escape characters that may have a special meaning (like single-quote, double-quote, and the backslash itself). >>> "wt\"f" 'wt"f' In a raw string literal (as indicated by the prefix r), the backslashes pass themselves as is ...
\[(.+)\]matches any sequence of characters wrapped in square brackets. The capture group picks out the username string, for instancejohndoe. [-T:+\d]{25}matches the time stamp, which you explored in the last section. Since you won’t be using the time stamp in the final transcript,...
So far, we’ve looked at the string object’s sequence operations and type-specific methods. Python also provides a variety of ways for us to code strings, which we’ll explore in greater depth later. For instance, special characters can be represented as backslash escape sequences: >>> S...
Like tuples, lists, and ranges, strings are also sequences because their items or characters are sequentially stored in memory.You can use the in and not in operators with strings when you need to figure out if a given character is present in the target string. For example, say that you...
